Referring to Figs.- l and 2,* thel machine To (LZ/ whom tl may concerny Beit known that'we,'CHARLEs B. MODON- i rALI) and CHARLEs D. MCDONALD, citizens of "the United States, residing at Chicago, in thc 5j count of Cook and State of Illinois, have in'- `vente certain new and useful Improvements 1 in Can-Soldering Machines, of which the'following is a specification. i

` l This 'nvention relates to machines for solmaryobject to provide means for varying In solderin some cans it is desirable' that.

j .The'machine isadapted` to automatically solder both ends of the can by 'a continuous.` v4o operation'andfinall-y. deliver the cans clean.

The invention relates to the' construction, arrangement, .and voperation of the rotatin mechanism forthe cans and tothe genera l arrangement and construction ofthe various p'artscomposing the machine foradapting the machine to operate rapidly and' unformly andwith a minimum `expenditure of p0Wer-" y; The invention consists in the'features of construction and combination of .p arts here-I In the .draWings,Figure 1 is a side elevar rfnttioally coated Withacid or resiny prior to the 3o S0 box 3.

` theA acid an Its sprocket-wheels 13 and 14 at opposite ends, and the carrier sprocket-chain is provided at suitable distances with arms 15, provided at their ends with rollers IE-for contactin the cans and lessening the friction anda W- ing the cans to roll more uniformly. The' sprocket-wheels 13 are mounted upon a shaft 17, and the sprocket-wheels 14 are mounted upon the shaft 18. The shaft 18 is journaled within a movable block 19, mounted within a frame 2G, and adapted to be adjusted within the. frame as a guideway b means of an adjusting-screw 21 and han -wheel 21, which allows the journal-block to be retracted and the sprocket-chains tightened to any desired degree. The frame at its forward end is slidably mounted upon a post 22, having an enlarged. head 23, provided with a lug 24, through which is entered an adjustingscrew 25, which is revolubly held within the frame 20 and has on its end a hand-wheel 25, by means of which the vertical elevation of the frame 20 can be regulated when desired.

" The shaft 17'is journaled within a slidable elevation above the acid and solder boxes alon which the cans are adapted to roll beheath the lower trackway. The shaft 17 has thereon a gear 34, which meshes with a 4 gear 35 on a shaft 36, which latter is provided with a sprocket-wheel 37, carrying a sprocket-chain 3 8, which passes around a sprocket-wheel 39 on the shaft 11 for actuating the sprocket-wheels 9, which move the hoists. As the carrier sprocket-chains are moved around the upper and lower trackways the hoists will be likewise actuated to deliver the cans which are moved along by thearms 15, space being allowed between the adjacent arms for a `single can, and the Wheels on the arms serve to minimize the friction andeause a rotation of the cans to distribute the solder evenly and uniformly around the edges. rlhe shaft 18' at the iiiner end of the cahier-chains has thereon a sprocket-wheel 40, over which passes a sprocket-chain 41, which is actuated 'by means of a sprocket-wheel 42 on a powershaft 43. The power-shaft has thereon fast and loose pulleys 44 of the usual character,

which are adapted to receive a belt, (not shown,) and t e belt passes between the -arms 45 of a guide 46, which is slidably mounted Within a frame47, extending transversely of the machine and provided on its opposite ends with handles 48, so that the power can be controlled from either side of prethe operatabsorb'ent substance 52, Isuch as waste or' lampwick, which is adapted to be moistened by a suitable acid composition delivered to j the absorbent substance through a pipe 53,

communicating with an acid-tank 54, having a valve 55 to control the flow oi acid. Both of the acid-boxes are supplied from the same tank, a pipe 56 serving to supply the farther acid-box with the necessary acid composition. Each of the acid-boxes is provided on its top with a guide-fiange 57, set in oblique relation to the upper surface of the acid-box, between which flan es a can is adapted to roll on its edge. rliis arrangement brings one edge of the can against the moistene'd absorbent projecting from the slot between the iianges 51 and meistens the edge. of the can as it is rolled along preparatory to being soldered. It will be understood that the guide-flanges on `the companion acid-boxes are set or tilted at a reverse angle to one another, so that on the return trip the cans will be held in reverse relation to the position they occupied on the initial tri through the machine, thereby mistening t e previouslyunrnoistened edge of the can preparatory to iinal soldering.

.The solder-boxes are located in line with the acid-boxes, so that the cans are rolled directly from one to the other, as shown in Fig. 4, each of the solder-boxes consisting of a receptacle 58 for containing solder 59, and

Athe machine. The sprocket-chain 41 asses IOO beneath said receptacle is a heating-space 60, adapted to be heated by burners 6I, conneeting with a header-pipe 62, which su plies gas or other heating substance to tllie under portion of the solder-boxes. The solder-boxes are provided with inner flanges 62, which overhang the inner walls of the IIO solder-boxes, and the boxes are further rovided with outer adjustable plates 63, w iich are hinged, by means of pivots 64, to fixed flanges 65 on thev outer side of the solder-box, which arrangement allows the angle of theplates 63 to be varied by means of adjustinvscrews 66. This adjustment ser'ves to ti t the cans .o a greater or less degree during their passage over the solder-box, so that the solder may be applied either equally to the bottom and side of the can or to one portion of the can to a greater degree than to the other. 'lhe solder is supplied to the solderbox through a feed trough or opening 67 (shown in Figs. l and 2) and flows down into lace iu the solder-boxes, where. it is heated liy means of the burners previously referred to.

lhe mechanism heretofore described is suitably 'supportedupon side rails 68, carried by uprlghts 691of any suitable character.

previou'sl mentioned, the cans are fed ""through the acid and solder boxes on edge to. 5 a'greater'or less degree; but when delivered to the brush-lb'ox-it 1s desirable that the cans vf travel f through on their ends rather' than fthe sides, and vin order to turn the cans, prior to theirdelivery to the brush-box the cans are made to slide downftheinclined fslidewaiyfi at the 4terminal. end l offthe.' solder-box, yw 'ech ideway A consists of rods 70, suitably bent or urned so to? twist the can during its' `de scent to. the brusheboxf'and deliver the can to yremovably secured to the lowerfsection.

'In order t at the ljournal-boxes at both ends of the brush may e uniformly ad'- justed, said journal-boxes are connected by means of a conneetin -bar 109, which eX- vtends4 from end to en of the brush at one A side thereof. The sleeves 105 at the frear end 1 .of the brush-box serve as mountingsfor shafts '110, which pass throughI and are 'ournaled within thel sleeves; ASaid shafts ave on Atheirinner ends gear-wheels 11.1, which ,mesh with gear-wheels 1.12, carried by the brush-journals 103, .which arrangement alof set-screws 114, passing throuda ears 115,

-brush-box and which journals are similar to those hitherto described. Rotation is imparted to the inner-brush journals through the medium of shafts 119 and intermeshing gear-wheels 120 and 121, similar in all ref spects to those hitherto described, and the front and rear inner journal-boxes are connected by bars 122, similar in. function and general arrangement to the connecting-bars 1/09. The short gear-shafts 110 and 119 are all provided on their ends with bevel-pinions 123, which are in the same vertical plane and mesh with. bevel-pinions 124 onl a transversely-extending shaft 125, journaled within brackets 126, and the shaft is provided on one end with a pulley-Wheel 127 for imparting rotation thereto.

The operation of the machine will be partiallyunderstood from the foregoing description, but may be briefly stated as follows:

The cans are fed into the rivht-hand hoist at.

the forward end of the machine, which is being constantly driven at a rate of speed uniform with the traveling sprocket-chain, and after being hoisted u onto the trackway formed on the top of t e acid-box are rolled along slightly on edge and have one edge smeared with acid or suitable composition to secure the adherence of the solder, and after passing over the acid-box they are rolled onto the solder-box and kept in constant rotation during their travel over the solder-box by the contact of the rollers on the ends of the carryin -armsl The solder in the box projects slig itly through the crack or space formed between the guide-plates, which cover the edge of the tilted can with solder, and the application of the solder will be uniform at al points, since 'the can is being constantly rotated in its travel from one end of the sold er-box to the other. After the can has been discharged from the solder-box it will roll down the trackway, as shown in Fig. 1, which. trackway is formed to twist the can sufliciently to throw it onto the lat end which has just been soldered, and the can carried forward by the friction of the endless belt into and through the brush-box. -In passing through the brush-box the outer brush onone side, which is rotating in the direction of theiarrow in Fig. 6, serves to rub oil the surplus solder on the bottom of the can and throw the same down into the body of the brush-box, and the coperating inner brush,

seance which is moving in' reverse relation to the outer brush, acts against the constantly-rsvolving curved side of the can to remove the surplus solder at that point. In this manner all of the sur A lus solder will be removed from both the si e and bottom of the can and thrown down into the bodv of the brush-box for future collection and yremelting. The relative position of uhe brushes can be varied to meet the requirements of cans of different size and shape, which adjustment can be quickly and easily made without unm'eshing any of the gears or changing the position or adjustment oi the operating mechanism. After the cans have passed through the brush-box they are'delivered onto the cooling-table and moved alonon the endless be t or apron prior to their ischarge onto the runway, and during their travel along the cooling-table and down the runway the solder is given a chance to harden rior to the second trip of the can throu h t e machine. The second trip of the can t irough the machine serves to solder the o poslte end, so that after the can has been discharged onto the cooling-table for the second time it will be com lete and ready for final discharge at the en( of the cooling-table. ,i

It will be seen from the fore oing description that the machine as a whole is simple 1n construction and that the various mechanisms for feeding the cans through-the machine are operated with the expenditure of a slight amount of power, which is applied at a suit able point and is constantly under the control o the operator. The arrangement pro vides a continuous cans, so that when t e cans are finally dclivered from the machine they will be in perfeet shape and read for use. The various operations are entire y automaticand no supervision is required beyond feeding the cans into the machme at a suitable rate and removing the cans after their final discharge from the machine.

Although the invention has been described with considerable particularity aste details and as to the method ot feeding 'the cans along the machine and discharging the cans therefrom and also with respect to the mode of transmitting the power to the various mechf ath of travel for thel IIO anisms, it will be understood that these eatures can be changed or modified and the power applied and distributed in any suitable manner without departing from the spirit of the invention.
